This enrichment and mouse transfer tube is designed to support low-stress handling and improved animal welfare. Tunnel handling is a proven method for reducing anxiety during transfers, offering a calmer alternative to traditional handling techniques. Constructed from durable polycarbonate, the tube withstands the high temperatures of autoclaving while maintaining its shape for long-term use. It also doubles as an enrichment device, encouraging natural behaviors within the cage environment. Reliable, reusable, and easy to sanitize, this transfer tube is a practical tool for both animal care and efficient workflow in the lab. Available in 100mm length x 50mm diameter and 130mm length x 50mm diameter tube sizes.
